I frequently never go bed till 2am, usually wake a number of times in the night,then 'wake' finally about 7am. Have a lay-in for an extra hour or so thinking of the worlds troubles, then up for breakfast and let the dog's out.
Due to past occupations and activities, always been a reluctant sleeper. Being retired now, I can now make a choice, with perhaps the occasional cat-nap during wakening hours!.
A number of years ago, this forum had what was called the Lounge, and many a conversation were held in the small hours, now I just lurk, and see what others have to say ;o).
